SIGNAL-LAMP CASING.

Specication of Letters Patent.

Patented Mar. 4L, 1919.

Application led March 2, 1917. Serial No. 151,874.

To all 'whom t may concern:

Be it known that I, JAMESr OHRT, a subject of the Emperor of Germany,resident of Paxton, county of Ford, and State of Illlnois, have inventedcertain new and useful Improvements in Signal-Lamp Caslngs, of which thefollowing is a specication.

My invention relates to improvements 1n lamp casings, particularly tolamp. casings principally intended for use with signals at railroadcrossings. l

Itis the object of the invention to provide a lamp casing in whichsignals, displayed upon the transparent walls of the casing, areilluminated by lamps within the casing and located in a circuit with abattery also arranged within the casing, and adapted to glow upon theclosing of the circuit by means situated outside of the casing, andadapted to be operated for instance by a moving train.

These and other similar objects are attained by the novel constructionand arrangement of parts hereinafter more fully described and shown inthe accompanying drawing, in which:

Figure 1 shows a lamp casing constructed according to the presentinvention with the cover removed, in section on line '1 -1 of Fig. 2.

Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1, and

Fig. 3 is a side elevational view showing one exterior wall of thecasing withl a signal displayed thereon.

The lamp casing according to the present invention includes a frame 20adapted to be suspended in any suitable manner, and bearing on itstransparent walls signals, for instance as shown, the word Stop or asimilar inscription, adapted to call the attention of people about tocross a railroad track to the proximity of an approaching train, etc,

The frame 20 is preferably made rectangular as shown, and the casingformed thereby contains a plurality of battery units 22, and a bracket21 secured to the upper side of the casing spaced therefrom. One

end of the bracket 21 is extended to the side wall as shown at 26 and isin engagement with the upper wall. Alining openings in the upper wall ofthe casing and bracket are closed by insulated blocks 27 having recessestherein engaging opposite sides of the casing and bracket, and sleeves28 of insulating material pass through the openings in casing andbracket and their ends are located within the recesses formed in theblocks. Lamps 24 are secured in suitable sockets in the bracket 21, anda conducting wire 23 connects the lamps with the battery units in thewell known manner, while one of its ends is guided through one of thesleeves 28 to a binding post 29. A conductor 31 connected to the batteryunits is also passed through a sleeve 28 to a binding post 30 at theoutside of the casing. Other conductors 25 and 32 are secured to saidbinding posts, so that any convenient means located outside of thecasing may be used for closing a circuit over the lamps within thecasing, which closing means may for instance be operated from anapproaching train in any well known manner.

Having thus described my invention, what I claim is:

In a device such as described, a casing, a bracket secured to the upperside of the casing spaced therefrom, one end of the bracket extending tothe side wall 0f the casing in engagement with the upper wall, saidbracket and upper wall having alining openings therein, insulated blockshaving recesses therein engaging opposite sides of the casing andbracket, sleeves of insulating ma terial passing through the openings inthe casing and bracket, with their ends in the recesses in the blocks,lamps carried by the bracket, batteries within the casing, a conductorconnecting the lamps and batteries, and conductors leading from thebatteries and lamps through the sleeves, as and for the purposes setforth.

In testimony whereof I have affixed my signature this 13th day ofFebruary, 1917.

JAMES GHRT.
